Split Vibration Damper Assembly for Retrofit Wiring Harness Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration dampers for motor vehicle wiring harnesses are difficult to mount and retrofit, and often require a housing or other structural components, which limits their installation flexibility and maintenance.
Innovation Solution
A vibration damper with two damper halves that enclose a passage opening and feature latching means, such as collars and latching hooks, allowing for easy attachment to a component using cable ties, enabling retrofitting and easy release without damage, and incorporating a metal core with thermoplastic encapsulation for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a cylindrical housing is used to hold damper halves together, then the vibration damper can be constructed, but it cannot be mounted on a shaft retrospectively and requires additional housing components
Solution Approach 1:
The vibration damper is divided into two separate damper halves that can be independently positioned and attached to the shaft. This segmentation eliminates the need for a enclosing housing while allowing the damper to be mounted retrospectively on existing shafts in older vehicles.
Solution Approach 2:
The housing component is completely removed from the design. Instead of enclosing the damper halves in a cylindrical housing, the invention uses only the essential damper halves with integrated collars for attachment, simplifying the structure and enabling retrofitting.
2Stability of the object's composition
If damper halves are held together by a cylindrical housing, then the structure is stable, but the mounting process becomes complex and time-consuming
Solution Approach 1:
The damper is segmented into two halves that can be independently installed on opposite sides of the shaft. This allows for quicker installation without requiring assembly of a housing structure, reducing mounting time while maintaining structural stability through the distributed attachment points.
Solution Approach 2:
The collars are pre-integrated into the damper halves during manufacturing, with latching means already prepared. This preliminary preparation eliminates the need for additional housing components during installation, allowing for rapid mounting while ensuring structural stability.
3Ease of manufacture
If a housing is used to enclose damper halves, then the damper structure is complete, but retrofitting in older vehicles becomes difficult
Solution Approach 1:
By dividing the damper into two separate halves that attach externally to the shaft, the design achieves structural completeness without requiring a enclosing housing. This segmented approach allows the damper to be adapted to older vehicles with existing shaft configurations.
Solution Approach 2:
The housing is extracted from the design entirely. The damper halves themselves form the complete structural solution when attached to the shaft, eliminating the need for additional housing components and enabling retrofitting in older vehicle models.
4Ease of operation
If collars with latching means are used to attach damper halves, then the vibration damper can be easily mounted and released, but additional attachment components are required
Solution Approach 1:
The collars are merged with the damper halves as integrated components rather than separate attachments. The latching means are built into the collars themselves, combining the attachment function with the existing structural elements and avoiding additional complex components.
Solution Approach 2:
The collars serve multiple functions: they provide structural support for the damper halves, enable attachment to the shaft through latching means, and allow for easy release and reattachment. This multi-functionality reduces the need for additional specialized components.

AI summary
A vibration damper is proposed with two damper halves which enclose a passage opening in the assembled state and, in the installed position, bear against a component which is guided through the passage opening. The damper halves have corresponding latching means which permit an attachment of the vibration damper to the component. Each damper half has in each case one collar, which collars, in the assembled state of the vibration damper, are arranged at opposite ends of the vibration damper. The vibration damper can be mounted simply, even retrospectively. Moreover, the vibration damper can also be released again without damage.
